The Argo is Fizik's most versatile saddle shape, meant to fit a wide range of riders, and the Vento R3 model is ideal for training and racing, with its ergonomic design and lightweight nylon shell. The ergonomic center cutout and dropped nose design prevents numbness and pressure on soft tissue so we can focus on our pedal stroke, while the reactive foam padding optimizes power transfer and rider comfort. Fizik's R3 shell with ride-compliant carbon-reinforced nylon and Kium hollow rails enhances comfort for the tough training sessions.
